SPECIFICATION forming part o'f Letters Patent No. 352,709, datedNovember 16, 1886. 7

Application filed March 27, 1886. Serial No. 196,935. (No model.)

York, have invented a new and useful Improvement in Vessels, of whichthe following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of my improve- 3 is a rear elevation'of thesame, the rudders being removed.

The object of this invention is to promote safety, stability, and speedin vessels.

My invention consists in a vessel having a rectangular contour in planand in transverse cross-section and double convex in longitudinalcross-section and side elevation; also, in certain detailsoficonstruction, as will be hereinafter described and claimed.

The measurements given in the following description are to regarded assuggested proportional dimensions; but the vessels can be built of anydesired size. The hull Aof the vessel is made one hundred and eightyfeet long, with flat vertical sides B twelve feet high at their middleparts and tapering to a point at or near the water-line. The hull A issixty feet wide, and with its bottom 0 flat in cross-section, butcurving gradually upward from its middle part to the ends of the sidesB. The middle third, D, of the upper side of the vessel A is fiat, toserve as a deck, and is surrounded by a combing, E. The end thirds, D,of the upper side of the vessel gradually incline or curve downward fromthe ends of the deck D, and meet the ends of the bottom 0 at a sharpedge.

The vessel is provided with two or more drop or stationary weightedkeels, F, as the breadth of the vessel may require, to prevent thevessel from having a side slip or movement in the water. placed beneaththe lower edge of each vertical side B, as indicated in Fig. 3.

In all cases a keel, F, is'

width of the vessel may require, the said rudders being controlled byrudder-chains H or other well-known appliances for this purpose, so thatthe vessel can be readily guided.

Two or more masts, I, can be used, as the length and breadth of thevessel may require,

some of the masts being placed abreast, if desired.

.The vessel can also be driven by steampower, two or more side wheels orscrews being used, as may be required, to give the vessel any desiredspeed. When screws .T are used, they are placed beneath the stern, asindicated in dotted lines in Figs. 1 and 2 and shown in full lines inFig. 3. 0

If desired, a screw, J, can be placed beneath the rear part of a wing orextension built upon each side of the vessel, and. not extending so farback as the stern of the vessel.- The interior of the vessel is designedto be divided up into a number of water-tight compartments.

A vessel thus constructed will have great breadth of beam in connectionwith a very fine entrance and run. As awar-vessel this. constructionwould produce a most formidable ram, and would have unequaled steadinessas a gun'platform.

Having thus described my invention, I claim as new and desire tosecureby Letters Patent 1. A vessel having a rectangular contour in planand transverse cross-section and double- WILLIAM LOUIS DILLON OGIIADY.
